The operation feeling is the primary objective for the development of EX-RR. It is the operation feeling which operates the car. We think that the feelings which can not be evaluated are as important as the numerical value in each steering, throttle and software element.

Direct throttle feeling has been improved.

The newly designed throttle unit has increased the direct feeling.

Renovating the form by lengthening the throttle trigger and operational angle.
In order to not influence the operational angle, the distance to the finger from the angular sensor has created a more direct feeling while maintaining a compact and comfortable size. With the direct feeling of the throttle/brake reaction when moved, the increase of this linear feeling allows for a smoother and quicker reaction with input on the throttle and brake.

Spring Tension Adjustment.

Trigger spring tension = personal preference. The new trigger unit provides a spring tension adjustment with a screw. This allows for a stronger or softer spring tension according to personal preference.

The long life period of the angle sensor’s smoothness does not change.

The new angle sensor used has proven to give a precise signal and shown durability. Because the signal is very precise, delicate movements are very fluid. The durability of the new sensor has shown approximately an improvement of 100 times over the past sensor used. Small operation feeling of the fingertip translates into a smooth and linear output to an ESC and servo.

Smoother steering unit.

The soft spring which can be operated with a constant tension.

The normal spring included in the extension unit has been modified. The previous spring used was a progressive spring becoming stiffer as the wheel angle increased, but the new softer spring give a linear stiffness as the wheel angle increases. Since the spring tension can be adjusted, you can set the spring tension to your personal preference.

Small diameter of the wheel / The operation feeling improves with the lightening of the wheel.

The newly designed wheel is made from aluminum. Multiple run test were iterated and the best wheel diameter was chosen. Becoming a little smaller then previous wheels the reaction of the car operation has improved. The diameter of the aluminum wheel is 2mm smaller and the weight is the same as a plastic wheel. Therefore, it has the rigidity of aluminum but a light operation feeling.

The sponge material has an exquisite grip feeling.

The sponge material has also been changed to improve the feel to the fingers. The increased comfort gives the impression of the fingers grasping securely even during a long race.

The evolved software

Calculator has rollout calculation.

FUNCTION>SYSTEM>CALC

This new function has been added to the calculator in the EX-2. Put TYRE DIAMETER in the calculator, ROLLOUT( Car movement distant per one motor rotation ) is automatically calculated. This is useful for changing gearing in a DD car.

New Push Control Function for Direct drive car.

THROTTLE>(PAGE2)>PUSH

A motor that has a strong magnetic force will add a braking effect when the throttle is released and will make a car stall in the corner. Setting the amount of forward input to remain on the throttle as the trigger returns to neutral can be adjusted. This is effective for F1, WorldGT and 1/12 category of cars whose gear ratio is small.

English?Japanese language change is possible in the menu.

FUNCTION>SYSTEM>CONFIG

You can change language in the display from Japanese and English. Selecting the display language that you prefer to use.
